feat req: Parse tracker input

[ywwa]

Currently when adding player to tracker, field accepts any input no matter what. what results to tracker being completely broken (you cant,remove entry from tracker or delete tracker by itself)

What could be better solution is parsing provided input, for example if you provide steam profile url it will trim down everything but steamid, or give error saying that its not valid input and same applies to battlemetrics as well

i will look into that. Thanks for the report
